Features and Benefits
Simple, Economical Installation
• Standard sound levels are roughly 5-8 dBa less than the previousTrane air-cooled models,
perfect for applying outdoor HVAC equipment in neighborhoods, such as K-12 schools.
• System integration available with LonTalk
®
or BACnet
®
through a single twisted-pair wire for
a less expensive translation to an existing building automation system.
• Powder-coated paint provides superior durability, corrosion protection, and is less likely to be
damaged while rigging/lifting/installing the chiller.
• Factory commissioned unit-mounted starter reduces overall job cost and improves system
reliability by eliminating job site design, installation and labor coordination requirements.
Precision Control
• Easily integrated with existing BAS via BACnet or LonTalk communication interfaces.
• Microprocessor-basedTrane CH530 controls monitor and maintain optimal operation of the
chiller and its associated sensors, actuators, relays, and switches, all of which are factory-
installed and tested prior to shipping.
• Adaptive Control maintains chiller operation under adverse conditions, when many other
chillers might simply shut down. Operating conditions that are compensated for include high
condensing pressure and low suction pressure.
• Advanced microprocessor controls enable variable primary flow applications providing chilled
water temperature control accuracy of ±2°F (1.1°C) for flow changes up to 10 percent per minute,
plus handling of flow changes up to 30 percent per minute with continuous operation.
• Easy-to-use operator interface displays all operating and safety messages, with complete
diagnostics information, on a highly readable panel with a scrolling touch-screen display.
Status and diagnostic messages are in plain language - no codes to interpret - and are available
in 20 languages.
Improved Serviceability
• All major serviceable components are close to the edge. Service shutoff valves and water
strainer are conveniently located to enable easy service.
• Water piping connections are factory piped to the edge of the unit to make installation safer and
faster.
• Electronic expansion valve designed so controls can be removed and serviced without
refrigerant handling.
• The optional pump package is designed to be serviced in place.The unit structure includes a
rigging point for pump servicing, making inspection, cleaning and pump seal changes easier.
• High pressure transducer and temperature sensors mountings enable troubleshooting and
replacement without removing refrigerant charge, greatly improving serviceability over the life
of the unit.
• Dead front panel construction provides for enhanced service technician safety.
